Aside from the IMAX premiere, two character from the X-Men franchise will likely have their first live-action appearance as X-23 and Omega Red are rumored to join "Wolverine 3", Cinemablend reported.
X-23 is the female clone of Wolverine created by an organization known as "The Facility" to recreate the Weapon X program. She has the same powers as Logan and has undergone the same adamantium bonding experiment. Omega Red is a dangerous Russian mutant from Logan's past as he hunts the feral X-Men for the carbonadium synthesizer which enhances his natural powers.
